Adult stem cells provide a promising alternative for the treatment of decompensated liver cirrhosis. Our previous study showed that peripheral blood monocytes (PBMCs) from decompensated liver cirrhosis could differentiate into hepatocyte-like cells in vitro. We here aimed to investigate the differential potential of the PBMCs under liver environment. PBMCs were isolated from one cirrhotic patient, who was mobilized by the recombinant human granulocyte colony stimulating factor for consecutive 3days, and then PBMCs were transplanted into nude mice by tail vein after labeled with PKH26-GL. The location of the transplanted PBMCs was identified by PKH26-GL staining and PRINS for human SRY gene. The expressions of human hepatocyte-markers were detected by immunohistochemistry, RT-PCR, and Western blot analysis. Our results demonstrated that PBMCs from decompensated liver cirrhosis could migrate into the liver of nude mice with human hepatocyte-markers expression, indicating that autologous PBMCs transplantation might be one alternative therapy for the decompensated liver cirrhosis.
成体干细胞为失代偿期肝硬化的治疗提供了一种有前景的替代方法。我们之前的研究表明,失代偿期肝硬化患者的外周血单核细胞(PBMCs)在体外可分化为肝细胞样细胞。我们在此旨在研究肝脏环境下PBMCs的分化潜能。从一名肝硬化患者中分离PBMCs,该患者连续3天接受重组人粒细胞集落刺激因子动员,然后将PBMCs用PKH26-GL标记后经尾静脉移植到裸鼠体内。通过PKH26-GL染色和人SRY基因的引物原位标记法(PRINS)确定移植的PBMCs的位置。通过免疫组织化学、逆转录-聚合酶链反应(RT-PCR)和蛋白质免疫印迹分析检测人肝细胞标志物的表达。我们的结果表明,失代偿期肝硬化患者的PBMCs可迁移到裸鼠肝脏并表达人肝细胞标志物,这表明自体PBMCs移植可能是失代偿期肝硬化的一种替代治疗方法。
